Understanding the Challenge

The Living Building Challenge is composed of seven performance areas, or ‘Petals’: Site, Water, Energy, Health, Materials, Equity and Beauty. Petals are subdivided into a total of twenty Imperatives, each of which focuses on a specific sphere of influence. Explore each Petal and Imperative.

This compilation of Imperatives can be applied to almost every conceivable Typology, or project type, be it a building (both renovation of an existing structure or new construction), infrastructure, landscape or community development. Naturally, strategies to create Living Landscapes, Infrastructure, Renovations, Buildings or Neighborhoods will vary widely by occupancy, use, construction type and location – this is necessary – but the fundamental considerations remain the same.

Each project must identify its Living Transect, or intensity of development surrounding its site. There are six Living Transects, ranging from Natural Habitat Preserve to Urban Core. Learn more.

Two overarching rules govern Standard:

1. All Imperatives assigned to a Typology are mandatory. Some Typologies require fewer than twenty Imperatives because the conditions are either not applicable or may compromise other critical needs. However, teams are encouraged to integrate the optional Imperatives into their projects wherever possible. Refer to the Summary Matrix to view the list of Imperatives that are mandatory for each project type.

2. Living Building Challenge certification is based on actual, rather than modeled or anticipated, performance. Therefore, projects must be operational for at least twelve consecutive months prior to evaluation.
